I will discuss the data processing and data handling of the CFHTLenS and KiDS collaborations. Special emphasis will be given on our algorithms and processing methods for weak gravitational lensing studies. I will summarise the current status of our image processing pipeline THELI which is optimised to produce lensing quality data from current and future optical Wide-Field Imaging Surveys. Our software suite encompasses all necessary modules from raw images to multi-band object catalogues with photometric redshifts and galaxy shapes. The talk will be complemented with a summary of the lessons we learnt in the past 15 years to successfully implement and execute an optical Wide-Field Imaging survey.
